800149a7 - riscv: sifive: Apply errata "cip-453" patch

Mon, 22 Mar 2021 14:26:05 +0000

riscv: sifive: Apply errata "cip-453" patchAdd sign extension to the $badaddr before addressing the instruction pagefault and instruction access fault to workaround the issue "cip-453".To avoid affecting the existing code sequence, this patch will creates twotrampolines to add sign extension to the $badaddr. By the "alternative"mechanism, these two trampolines will replace the original exceptionhandler of instruction page fault and instruction access fault in theexcp_vect_table. In this case, only the specific SiFive CPU core jumps tothe do_page_fault and do_trap_insn_fault through these two trampolines.Other CPUs are not affected.Signed-off-by: Vincent Chen Signed-off-by: Palmer Dabbelt List of files: /linux-6.15/arch/riscv/errata/sifive/Makefile
